CVE-2026-93063

Estado: RecibidaAlta (8.4)—

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: mei: check SAP message length before reading it

Verify the SAP message size is not larger than the local buffer before reading the message to avoid buffer overflow.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 8.4

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.21%
Percentil entre todas las CVEs puntuadas: 10
Fecha de la puntuación: 2/10/2026

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
